Debian DLA-1604-1 : lxml security update

medium Nessus Plugin ID 119560

Language:

Synopsis

The remote Debian host is missing a security update.

Description

It was discovered that there was a XSS injection vulnerability in the LXML HTML/XSS manipulation library for Python.

LXML did not remove 'javascript:' URLs that used escaping such as 'j a v a s c r i p t'. This is a similar issue to CVE-2014-3146.

For Debian 8 'Jessie', this issue has been fixed in lxml version 3.4.0-1+deb8u1.

We recommend that you upgrade your lxml packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected packages.
